Abstract:
Disclosed herein is a system having a first housing that includes an optically transparent substrate having a first side and a second side that is opposed to the first side, a camera disposed on the first side of the optically transparent substrate and a source of illumination. The source of illumination is disposed in a ring on the periphery of the first housing and located on the first side of the optically transparent substrate. The system further has a second housing having a circuit board that is operative to process the image captured by the camera, and a battery pack that is operative to supply electrical energy to the source of illumination and to power the circuit board.
Abstract:
A gas outlet monitoring system for a boiler system includes a gas probe(s) with a plurality of gas sensing locations wherein each location measures a plurality of parameters of the gas flow, such a oxygen concentration and temperature. The multi-sensor probe includes a tubular lance and a plurality of sensor pods spaced along the lance. Each sensor pod has an oxygen sensor disposed in a first port, and a first temperature sensor disposed in a second port. An enclosure is disposed at one end of the tubular lance. The enclosure has a respective pressure sensor for each oxygen sensor port. A plurality of first tubes passes through the lance between the enclosure and the first port of a respective sensor pod to provide a gas to the respective first port for the purpose of providing cleaning air. A plurality of second tubes passes through the lance between the enclosure and the first port of a respective sensor pod to provide fluid communication between gas in the respective first port and the respective pressure sensor. One pressure sensor is provided for each oxygen sensor.
Abstract:
An apparatus is mountable to a duct having a cross-section, for determining parameters of a flowable medium flowing through the duct. The apparatus includes a mounting attachment having a conduit member, and at least one combination of multiple sensing members configured to the conduit member. The conduit member may be disposed entirely within the duct such that the multiple sensing members are located within the duct establishing direct contact with the flowable medium. The multiple sensing members include oxygen and temperature sensing elements respectively, to determine parameter such as oxygen level in the flowable medium, and temperature of the flowable medium. Several such apparatus may be mounted in the duct across the cross-section to define a grid to determine said parameter at various locations across the cross-section.
